John Mayer is getting very candid about his past relationships with Jessica Simpson and Jennifer Aniston. In a new interview with Playboy, the rocker compares Jessica to a drug and says he still loves Jen.

"That girl, for me, is a drug. And drugs aren't good for you if you do lots of them. Yeah, that girl is like crack cocaine to me. Sexually it was crazy. That's all I'll say," John told Playboy in its March issue when asked about his 2006 relationship with Jessica. "It was like napalm, sexual napalm."

John told the mag he felt addicted to the 29-year-old singer.

"There are people in the world who have the power to change our values. Have you ever been with a girl who made you want to quit the rest of your life?" he continued. "Did you ever say, 'I want to quit my life and just f****** snort you? If you charged me $10,000 to f*** you, I would start selling all my s*** just to keep f****** you.'"

In the interview, the rocker also dished on ex-girlfriend Jennifer Aniston, admitting that he's still in love with the actress and feels "very protective" of her.

"Do you still love her?" the mag asked.

"Yes, always. I'll always be sorry that it didn't last," John said. "In some ways I wish I could be with her. But I can't change the fact that I need to be 32."

The rocker won't reveal how much of his latest album, "Battle Studies," is about Jen, but says he hopes his music will relate to everyone's lives.

"I feel bad because people think 'Heartbreak Warfare' is about [Jen]. I want to go on record saying it's not. That woman would never use heartbreak warfare," he continued. "That woman was the most communicative, sweetest, kindest person. When people hear the record, I hope the songs make them think about their lives, not my life.

"We just have a regard for each other's feelings that is pretty intense. It's been a deep relationship, and it's no longer taking place at all," he said about the 40-year-old actress. "Have you ever loved somebody, loved her completely, but had to end the relationship for life reasons?"

John goes to deny reports that he and Jen broke up because he was Tweeting too much – though he does admit there was a technological divide in their relationship.

"One of the most significant differences between us was that I was Tweeting. There was a rumor that I had been dumped because I was Tweeting too much. That wasn't it, but that was a big difference," he explained. "The brunt of her success came before TMZ and Twitter. I think she's still hoping it goes back to 1998. She saw my involvement in technology as courting distraction."

The rocker also shot down reports that he's been involved sexually with men.

"The only man I've kissed is Perez Hilton. It was New Year's Eve and I decided to go out and destroy myself. I was dating Jessica at the time, and I remember seeing Perez Hilton flitting about this club and acting as though he had just invented homosexuality. All of a sudden I thought, I can outgay this guy right now," he reveled. "I grabbed him and gave him the dirtiest, tongue-iest kiss I have ever put on anybody – almost as if I hated f***. I don't think my mouth was even touching when I was tongue kissing him, that's how disgusting this kiss was. I'm a little ashamed. I think it lasted about half a minute. I really think it went on too long."
